About

🚀 Dominate Search Rankings with Visual SEO Insights

Stop staring at boring spreadsheets! Website Performance & SEO Analyzer transforms the way you audit websites by injecting visual insights directly onto the page. Whether you are an SEO professional, developer, or content creator, this tool gives you immediate feedback on what matters most.

🔥 Visual Overlays (The "Hook")

H-Tag Map: Instantly see the page structure. We draw colored boxes around H1, H2, and H3 tags so you can spot hierarchy issues in seconds.
Image Audit: Automatically highlight images missing "Alt Text" in Red and identify oversized images (>100kb) in Yellow.
Broken Link Validator: We scan the links on the page and visually mark potential broken links so you can fix them fast.
📊 Core Analysis

Meta Snapshot: Get a quick view of the Title, Meta Description, and Canonical URL with real-time character counting.
Core Web Vitals: Measure real-world user experience with live LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift) scores.
Social Preview: See exactly how your page will look when shared on Facebook, Twitter/X, and LinkedIn.
🕵️ Advanced Tools

Competitor Spy: "Peek Headers" to extract the entire heading structure of any competitor's article. Perfect for outlining your next blog post.
Technology Detective: Instantly detect the tech stack (WordPress, React, Next.js, etc.) used to build the site.
Keyword Density: Type any target keyword and watch the extension highlight every occurrence on the page with a total count.
Why choose this extension?

Modern, Dark-Mode "Glassmorphism" UI.
Lightweight and fast—doesn't bloat your browser.
Privacy-focused: We analyze pages locally and do not track your browsing history.
